Question 1127682
 Jordan uses the length of his hand to measure the size of his desk. He finds the top of his desk to be about "2.5 hands by 9.5 hands" in size. Summer uses her hand and finds the same desk to measure about "3.5 hands by 13.3 hands" in size. 
a. Jordan's hand is how many times as long as Summer's hand?
Equation:2.5j = 3.5s
Ans: j = [3.5/2.5]s
j = 1.4s
Jordan's hand is 1.4 times Summer's hand.
---------------------- 
b. What is the measure of Jordan's hand using Summer's hand as the "unit ruler"?
Jordan's hand is 1.4 times Summer's hand
--------------------- 
c. Summer's hand is how many times as long as Jordan's hand?
3.5s = 2.5j
s = (2.5/3.5)j
s = 0.71s
Summer's hand is 0.71 times Jordan's hand.
------------- 
d. What is the measure of Summer's hand using Jordan's hand as the "unit ruler"?
Summer's hand is 0.71 times Jordan's hand.
